( 7k - 3)  ( k^2 - 2k  +  7)  =

 

7k ( k^2  - 2k  +  7 )  =          7k^3  -   14k^2   +  49k

+                                       +

-3 ( k^2 - 2k  + 7)   =                          -3k^2    +    6k   -   21

_____________                  _________________________

 

                                             7k^3   -   17k^2  +  55k   -  21
